Lower back pain doesn’t need to be part of pregnancy. Acupuncture can help relieve this pain. An observational study on acupuncture treatment on pregnancy women with lumbopelvic pain (this includes lower back and hip pain) reported that 89% of women in the study reported a pain decrease after just 3 treatments. Patients were considered low risk and mostly under the care of midwives in New Zealand. Most received cupping along with acupuncture as part of their treatments.
